SAFETY-BRAKE.

Specification of Letters Patent.

Patented Mar. 18,1913.

Original application filed June 22, 1911, Serial No. 634,814. Dividedand this application filed October 31,

To all whom it may concern:

Be it known that I, VALENTIN STASCH, a citizen of the German Empire, andresident of Friedenshiitte, Silesia, German Empire, have invented a newand useful Improvement in Safety-Brakes, of which the following is afull, clear, and exact description.

The present invention consist-s of a device for stopping runaway truckson inclined railway tracks and consists substantially in a frame mountedbetween the rails and having a pivoted lever supported therein with ahooked upper end and a cam-shaped milled or toothed lower end, the saidlever being so supported that when the trucks or cars move up the trackthey will simply depress the same and pass over it, but if a runawaytruck gets loose and runs down the track, the hook of the lever willcatch or engage the axle or any other part of the truck and the leverwill be moved round its pivot, so that its cam-shaped end engages aplate mounted beneath the rails and will act as a brake, thus stoppingthe truck.

The present application is a division of my United States Patent No.1,031,152, issued July 2, 1912, Serial No. 634,814, filed June 22, 1911.

The invention is illustrated in the accompanying drawings, Figure 1being a sectional side elevation of the device showing the lever in itsoperative position to stop a truck, Fig. 2 is a similar elevation,showing the truck passing up the track in the direction of the arrow anddepressing the lever, Fig. 3 shows the lever in engagement with the axleof a runaway truck, Fig. 4 is a plan of the device, and Fig. 5 is across section, showing the plate and the manner in which it is attachedto the rails.

Serial No. 657,801.

The frame e carries a pivot a and may either be fixed between the railsor may slide on the same. Mounted on the pivot a is the brake leverhaving a hooked upper part b and a cam-shaped lower part 0 with a milledor toothed edge which is adapted to engage the plate (Z mounted beneaththe same under the rails.

As will be readily understood from the drawings, when the truck moves upthe track (Fig. 2) it will simply run over the lever b 0 but if arunaway truck (Fig. 3) runs down the rails in the direction of the arrow(Fig. 3) it will. engage the hooked end 6 of the lever and cause the camend 0 to contact with the plate cl so that the truck will either bestopped at once if the frame 6 is fixed or will be stopped gradually ifthe frame is adaptedto slide along the rails to the extent of the platecl.

I claim as my invention:-

A device for stopping runaway trucks or cars 011 inclined tracksconsisting of a frame mounted to slide on the track rails, a leverloosely pivoted in said frame between the track rails to normally extendupwardly, a brake rail beneath the track, said lever having means atits, upper end for engaging the truck and having means at its lower endfor engaging with the brake rail when the upper end of said lever isviolently struck by a runaway truck.

In testimony whereof I affix my signature in the presence of twowitnesses.
